“I’m just waiting for my number to be called, that’s it,” Bush said. “Wait for my opportunity and do the best I can to stay ready.”

With the Bills dealing with some injuries at receiver, Buffalo actually prepped Bush to play slot receiver if needed, but they never got him into the game at that position last week.

“The thing I really like about Reggie is, when [receiver] Greg [Salas], we saw late in the week, Greg has this groin injury, we said, ‘Well, for an emergency, we need to teach Reggie how to play the slot receiver,'” HC Rex Ryan said. “So we had plays designed for him to play the slot. We never got to it, but he was ready to go. That was impressive. I think for a guy, it’s tough because you don’t if you’re going to play or what, but you’ve got to be prepared, and he was.”

Bush, 31, is a former first-round pick of the Saints back in 2006. He spent five years in New Orleans before being traded to the Dolphins in 2011. After two years with the Lions, Bush signed a one-year contract with the 49ers before his 2015 season came to an early end.

Bush sustained a torn MCL that he suffered after slipping on the exposed concrete at the Rams’ stadium in St. Louis. The Bills signed him to a one-year, $1.5 million contract that includes another $1.5 million available in incentives.

In 2016, Bush has appeared in two games and has rushed for -4 yards on three carries.
